Serverless Stack

In our cdk we created like
```const app = new <http://cdk.App|cdk.App>();
new MyStack(app, "dev", {
});
new MyStack(app, "staging", {
});
new MyStack(app, "prod", {
});```
to deploy in different environments. In sst we don't need to do this anymore? we will just deploy using the
--stage parameter?

You can still follow this pattern if you prefer but we recommend using stages

definitely go for stages! and control things with env variables where needed :wink:

e.g. you want to allow auto-deletion of bucket on lower envs with destroy - but you wanna prevent deleting it on prod
